Chicago Transit Authority – Oracle E-Business Suite ERP
DTI’s Roles


DTI provided IBM, CTA’s system integrator during the initial implementation of the Oracle E-Business Suite, functional and technical E-Business Suite consultants in the financial system area. These consultants learned the business of the CTA and performed the following:


  • Required configuration and customizations to meet CTA’s need as a large city transit authority.

  • Interface development to connect E-Business Suite to the CTA’s internal systems and external third-party systems.

  • Performance testing to help ensure the system handled CTA’s volumes.

  • Integration testing to make sure Oracle’s EBS worked with the CTA’s other systems.

Based on DTI’s work for them in the past, the CTA brought DTI back as a subcontractor to AST in 2016 to assist in the update to EBS Release 12, which was successfully completed.
